As I am newbie here can I join any bounty? And if yes then what I get from it?.
Welcome to this forum... Yes you can join bounties... There are lots of bounty campaigns that you can join lije the following.
Signature campaign, Facebook campain, Twitter campaign- by participating on these or either on of these you can earn a lot of token depending on task you made and task given.
AirDrop campaign- this campaign is the easiest way to earn different tokens but not that much in amount, because tokens from AirDrop may have a high prize but you can only receive few of it or a low in price but you can receive much and more of it.
